The present invention relates to voltage modifying means. Morespecifically, the in vention relates to a voltage modifying means of thevibrator type.

It is one of the objects of the invention to provide a voltage modifyingmeans of the transformer vibrator type wherein I am enabled to multiplyor divide the voltage from a given source of supply through the mediumof a transformer vibrator circuit wherein I am enabled to dispense Withalarge amount of material to thereby effect a saving of both material andweight.

More specifically, one of the objects of my inventlon is to provide avoltage doubler of the transformer vlbrator'type dispensing with thesecondary winding of the transformer.

For the purpose of disclosing my invention, I have illustrated anembodiment thereof in the accompanying drawing, in which the figure is adiagrammatic view of the vibrator transformer system embodying thefeatures of my invention.

In the embodiment of the invention illustrated in the drawing, thevoltage doubling system comprises a transformer I having a splitinductance winding, comprising two sections 2 and 3. The winding isprovided with a center tap connected to one side of a battery 4.Preferably I provide a controlling switch for controlling the circuit.The opposite side of the battery 4 is connected to a vibrating reed orcontact member 5 adapted to vibrate between a pair of oppositelydisposed relatively stationary contacts land ll,'which are respectivelyconnected to the and terminals of the inductance winding.

A second vibrating contact member 9 is connected to an output lead ID.This reed 9 vibrates between a pair of oppositely disposed relativelystationary contacts H and i 2. The contact l l is connected to the endterminal of the winding section 3 and the contact 12 is connected to theend terminal of the winding section 2. The opposite side of the batteryl is connected to an output lead l3 between which lead and the lead H],the load may be connected.

The reeds 6 and 9 may be and usually are mechanically-connected tooperate in synchronism and the reeds are driven through the medium ofthe driving magnet l4 having a winding l5, one terminal of which isconnected to one side of the battery 4. The opposite terminal of thewinding i5 is connected to a relatively stationary contact l6 adapted tobe engaged by the reed 6 when the reed is in neutral position.Accordingly, when the switch 5 is in the closed position the reeds 6 and9 will be driven in one direction by the magnot H and into engagementrespectively with the and il, the circuit, through the Winding I5, is

broken permitting the reeds 6 and 9, under their momentum, to move intoengagement with the contacts 8 and I2 respectively. At the same time thecircuit of the magnet I4 is re-established. Accordingly the reed G isvibrated between the contacts l and 8 alternately making and breakingthe circuit between these contacts and likewise the reed 9 issimultaneously vibrated to alternately make and break contact with thereeds l l and I2.

With the reeds 6 and 9 respectively engaging contacts 1 and II andassuming that the battery 8 delivers 12 volts, 12 volts will be suppliedto a circuit including the battery, the winding 2, contacts l and theopposite side of the battery. Likewise 12 volts from the battery 4 willbe delivered from the plus side of the battery 4, in the oppositedirection, the contact H and thence to the plus output lead 10 andthence through the load by output lead l3 to the minus side of thebattery. However, due to the 12 volts delivered to the winding 2, 12volts will be induced in the winding 3 which superimposed upon the 12volts delivered from the battery will result in 24 volts being deliveredto the load. In other words, this voltage induced by the winding 2 inthe winding 3 will double the voltage of the battery to the load.

likewise when the reeds B and 3 are engaged with contact 8, the 12 voltsof the battery will be delivered to winding 3 from the plus side of thebattery 4 to the minus side of the battery 4 through the contact 8 andreed 6. At the same time 12 volts will be delivered to the winding 2 andthence by contact I 2 to the plus side I 0 of the load. At the same timewinding 3 will induce 12 volts in winding 2 so that actually there isdelivered 24 volts to the plus side ID of the load.

, It is, therefore, apparent that with the single induction winding I amenabled to double the voltage delivered to the load from the battery 4.It will be understood, of course, that the voltages referred to aremerely for the purpose of illustration as it is quite obvious thatbatteries delivering larger voltages than 12 volts may be used or anyother source of supply may be used other than the battery.
